DOING BUSINESS UNDER THE NAME OF BREWERY EQUIPMENT PLY` CO., OF NEWYORK, N. Y.

& SUP- TREFLSEPIPE BEERCOOL-ER.

To all whom, it may concern:

Be it known that I, WILHELM GRIEssER, a citizen of the United States,residing at Joplin, in the county of Jasper and State of Missouri, haveinvented new and useful Improvements in Triple-Pipe Beer-Coolers, ofwhich the following is a specification.

This invention relates to triple pipe beer coolers adapted to permit acontinuous circulation in separate pipes, respectively, of beer, brineand ammonia, the various pipes being arranged and connected at theirends to form a continuous coil, having an inlet at one end and an outletat the other.

The invention relates more particularly to an improvement in :heconstruction of the heads or bends connecting in alternate relation theopposite ends of the pipes of the coil.

In order that the said invention may be clearly understood I haveillustrated `vthe same in the accompanying drawings, in which:

Figure 1 is a side elevation of myimproved triple pipe beer cooler; Fig.2 is an end elevation; Fig. 3 is a vertical section on an enlarged scaleof one of the heads; Fig. 4 is a section upon the line 4 4 of Fig. 3;Fig. 5 is avertical section on an enlarged scale through a singlepipe-unit and head at the inlet or outlet end of the apparatus; and Fig.6 is a horizontal section of the same.

Referring now to these drawings, the numerals 1 indicate a series ofpipe-units arranged in parallel relation one above the other andsupported at their'ends in a manner to be described later on, and at acentral portion by moansof a frame 2. Each of the pipe-units 1 comprisesaninner pipe 3 for ammonia, an intermediate pipe 4, for beer, and anouter pipe 5, for brine. These pipes are concentrically arranged inspaced relat-ion, and, as will be seen, the beer will circulate in thespace 6 between the pi es 3 and 4 and will thus travel in a thin s eet,as it were, between the ammonia and the brine. The pipes of each unitare connected at 0pposite ends with the corresponding pipes of adjacentunits in a manner to aiiord a continuous circulation of the di'erentliquids employed throughout the entire series of pipes, and as all ofthese connections are the same, the description of one will suffice.

Referring now to Fig. 3, 7. indicates a hol- Specifcaton of LettersPatent. Application led February 19, 1906, Serial No. 301,887.

vwhich are screwed '5 of two adjacent units. These joints are Patented June 4, 1 907.

low head or casting having two parallel walls, namely, a rear wall 8 anda front wall 9,. affording between them a chamber 10. The rear wall 8 isprovided, toward its outer ends, with two screw-threadedy apertures intothe outer ends of the pipes made perfectly tight through the medium ofsolder 11. The pipes 5 are about five inches in diameter, in actualpractice, and are intended for the circulation of brine. yTheintermediate pipes 4 of the two units, connected by the head 7, areshown to project beyond the outer ends of the pipes 5, and their outerends are rolled and expanded, as indicated at 12, to be firmly securedin apertures formed in the front wall 9 of thehead 7. These pipes 4 areof j copper and areintended for circulation of beer. 13 indicates asectional cap which is applied to the front face of the head 7, thesections being recessed on their inner sides to form, when applied tothe head 7, a chamber 14 to provide for the circulation of the beer fromone pipe 4 to the next adjacent pipe 4. The two sections of the cap 13are indicated, respectivel by the numerals 15 and 16 and each of t esesections has at its outer edge three or more apertured lugs 17 by meansof which they are secured to the front of the headr 7. plished throughthe medium of bolts 18 which have a central plain portion adapted toseat in the apertures of the posite screw-threaded ends, one of which isscrewed into screw-threaded apertures of projections 19 on the front ofthe head 7 and the other of which receives nuts- 20 which bear against'the lugs17. The two sections 15 and 16 are divided vertically withrespect to the position of the apparatusshown and at their meeting edgeshave a tongue and groove connection 21, which connection will be furtherre-inforced by packing, as will be understood. The outer wall 9 of thehead 7 is provided with a continuous groove 22 into which is insertedmetal or other packing 23, and each of the sections of the cap 13 isprovided on its inner side with a` tongue 24 which'is adapted to seat inthe groove 22 and to be irmly pressed against the packing 23 by screwingup the nuts 20. Each4 of the sections 15 and 16 is provided withsemicircular recesses 25 which, when said sections This is accom? lugs1.7 and op-v TOO are placed together, form apertures 26 through whichthe innermost pipes 3 project. Each ol`v said sections l5 and 16 is alsoprovided on its outer side, above and below each of the semi-circularrecesses therein, with lugs 27 which are adapted to aline. Bolts 28 arepassed through these alining apertures and have nuts 29 applied to theirends for securing the two halves of the cap together. The pipes 3, asabove stated, extend through the sectional cap 13, which cap is providedin its outer face with recessed seats 30 surrounding the apertures 26and into which seats are inserted annular packing rings 31 which closelyembrace the pipes 3 and are firmly compressed into position by means ofsplit sleeves 32 affording an annular llance 33 which enters the seat 30and cngages the packing 31. Each of the sections of the sleeve 32 isprovided with a projecting` lug 34 in each of which is formed asemi-circular recess 35 and a bolt-hole 36. When thc two sections ofthesleevcs 32 are laced together about the pipes 3 the semi-circularrecesses 35 form apertures for bolts 36a, which have plain portionsseating in such apertures and opposite screw-threaded ends, one of whichis screwed into screw-threaded apertures formed in lugs 37 provided onthe front face of the cap 13, and the other of which receives nuts 3S bymeans of which the t sleeve may bc drawn into iirin contact with ythepacking 31 in the seat 30. Bolts 39, in-

serted through the bolt-holes 36 of the lugs 34, secure the two sectionsofthe sleeve 32 together and firmly clamp thcmabout the pipes 3. i

The outer ends of the pipes 3 are united by means of a rcturn-bcnd4()which permits circulation of thc ammonia from one pipe 3 to the nextadjacent pipe and this connection is made as follows: The outer en'dportion of each of the pipes 3 is screw-threaded and on thesescrew-threaded portions are screwed collars 41, the joint being madegas-tight at the rear sides of the cellars by means of solder 42. Theouter ends of the ipes 3 and the corresponding outer end portion of thecollars 41 are recessed to provideannular seats 43 into which seats areinserted metal packing 44. At oppogite ends of the return-bend theopening therein is surrounded by an annular iange 45, which flanges areadapted to be inserted in the seat 43 in contact with the metal packing44. The return-bend 40 is provided on opposite sides and near each endwith apertured lugs, 46, through the apertures in which are passedscrew-threaded ends of bolts 47 having hooked ends 48 engaging the rearsides of the respective collars 41. By means of nuts 43L applied to thescrew-threaded ends of the bolts 47 the return-bend 40 is drawn intofirm contact with t he ends of the pipes 3 and with the packing 44surrounding said pipes. The connection between the pipes 3 and thereturnbend 4 comprising the collars 41, irmly secured on the ends ofsaid pipes, is a very secure one and this is an important considerationas the pipes 3 are for the circulation ol' ammonia, and it is necessaryto prevent the possibility of the escape of ammonia around thescrew-threads of the pipes, which is accomplished by the solder 42, andat the connections between said pi es and the returnbend, which isaccomp is ied by the packing 44 and the manner of firmly drawing theflanges of the return-bend into contact with the said packing and theouter ends ol' the pipes 3. Owing to the firm and gas-tight connect-ionof the collarsy 41 with the iipes 3 it is not desirable to remove theseco lars at any time, and hence the construction described has in view topermit the pipes to be removed from the apparatus without it besin ingnecessary to remove the collars 41. l? or this purpose the Vcap 13 andthe sleeves 32 are made in sections. By removing the nuts from thebolts, by means of which these parts are connected tothe head 7 and tocach other, the sections of the cap 13 and sleeves 32 may be removedfrom about the pipes 3, and in a similar man-ner the return-bends 4 maybe withdrawn fromA the ends of said pipes in order that they may bereadilyA drawn through the pi e 4. to'permit`the -latter to be cleaned.ach of the heads 7 is provided on its front face,at each corner, withapertured lugs 49 so thatwhen said heads are placed one upon the otherthey may be unlted by means of bolts 5() passed through said aperturesandhaving nuts 51 IOO applied thereto,l th-e heads, when so united,

forming a stand or sup ort for'readily holding the pipe-units of t 1eapparatus in position at their outer e'nds. The lowermost head 7 at oneend ofthev apparatus-and the head 53 at the other have secured yto themstandards or bases 52 which rest upon the floor and support theapparatus as a whole in connection with frame 2. The heads 53 at therespective ends of the coil' are the same in construction as those justdescribed, eX- cept that it is only necessary that `they should providefor a single pipe-unit instead of for two pipe-units. The pipe 3 oi thelowermost unit 1 is suitably connected to a suction-pipe or ammoniaoutlet 54 whilethe head 53 of said unit is provided with a brineoutletpipe 55 and the cap 13 with a beer inlet 56. The upper unit 1 has'a pipe3 connected with an ammonia supply pipe 57 while its cap 13 is providedwith a beer outlet 58 and its head 53 with a brine inlet 5S).

While I have described a cooling apparatus intended more particularlyfor use in cooling beer, it will be apparent nevertheless that a seriesof pipes connected up as described can be utilized for heating purposesas well as for cooling for instance, steam could be IIS collars andscrew-threaded ends passed through theintermediate pipesfor the purposeol heating the water passing through the inner and outer pipes.

Having thus fully described my invention, y

what I c im as new and desire to secure by Letters Patent, is:
